Figures 2-15F and 2-15S show a detail similar to 2-14, executed with spray foam instead of rigid foam panels. The foam is applied from the top of the basement slab to the bottom of the subfloor above, encapsulating the sill and rim joist. The rim joist is also insulated by the exterior rigid foam on the above-grade walls, minimizing its exposure to cold temperatures and decreasing the likelihood of moisture damage. Like figures 2-14, interior fire protection is provided by paperless drywall attached to a framed wall.
